Signless Laplacian spectral radius of graphs without short cycles or long cycles

Wenwen Chen, Bing Wang, Mingqing Zhai

The signless Laplacian spectral radius of a graph $G$ , denoted by $q (G)$ , is the largest eigenvalue of its signless Laplacian matrix. In this paper, we investigate extremal signles…

Spectral extremal problem on $t$ copies of $ℓ$ -cycle

Longfei Fang, Mingqing Zhai, Huiqiu Lin

Denote by $t C_{ℓ}$ the disjoint union of $t$ cycles of length $ℓ$ . Let $e x (n, F)$ and $s p e x (n, F)$ be the maximum size and spectral radius over all $n$ -vertex $F$ -free graphs, re…
